METAL-REINFORCED CONCRETE PIPE.

Specification of Letters Patent.

Patented Dec. 23, 1919.

Application filed June 28, 1918. Serial No. 242,439.

To all whom it may concern:

Be it known that I, Jean C. POLING, a citizen of the United States,residing at Nebraska City, in the county of Otoe and State of Nebraska,have invented certain new and useful Improvements in Metal-ReinforcedConcrete Pipes, of which the following is a specification.

This invention relates to improvements generally in what may be termedmetal reinforced concrete or plastic pipes and more particularly blocksfor forming pipes or conduits or circular tubular bodies, espe cially ofthe larger or sewer-pipe type.

The invention has for its object to provide for effectively protectingall metal parts against corrosion or rusting and to provide for theinexpensive manufacture of the blocks and to promote durability thereof.

Other objects of the invention will be apparent as the character,advantages and uses thereof may be subsequently better understood.

The invention therefore consists of certain instrumentalities andfeatures of construction substantially as hereinafter more fully setforth and defined by the appended claim.

In the accompanying drawings is illustrated the preferred embodiment ofmy invention, wherein it will be understood that various changes andmodifications may be made as to the detailed construction andarrangement of parts without departing from the spirit or scope of myclaim, and in which drawings,

Figure 1 is a somewhat mutilated pcrspective view of an assemblage ofblocks or members for forming annular sections of a pipe, ascontemplated by my invention.

Fig. 2 is a plan view of a number of assembled blocks, showing moreparticularly the outer and inner arrangement of the constituent parts ormembers thereof.

Fig. 3 is a perspective view of a single block or section on an enlargedscale.

Fig. 4 is an enlarged plan view of a con nection between the metallicreinforcing members or bars of the blocks.

Fig, 5 is a detailed perspective'view of an individual member of saidreinforcing bar-joint-connection.

In carrying out my invention, 11 suitably mold or form a block orsection, designated generally as 1, adapted to form by arranging aplurality thereof together, a pipe, especially of the larger orsewer-pipe type. The block or section 1 is arcuate or concave in itsgeneral outline or contour and, in addition, is stepped at its ends,thereby forming overlapping terminals or shoulders 2 at those points toprovide overlapping joints between abutting or contacting blocks. Saidblock is also stepped in transverse section, resulting in producingalong its inner upper and lower edges, shoulders 3, and. along its outerupper and lower edges, shoulders 3*, said shoulders being adapted toform overlapping joints, at said points, with correspondingly formedshoulders of adjacent blocks in the pipe-formation.

The blocks or sections are suitably assembled, block to block, to forman annular or circular disposition thereof, with their end shoulders 2interlocking, while each annular or circular arrangement of blocks isopposed end to end, breaking joints with the aforesaid blocks orsections, the concaved tenon-like shoulders 3 overlapping each other,thus providing for building up or forming the pipe. The sections orblocks 1 may be assembled in any desired number, according to thediameter it may be required to impart to the prospective pipe. Also thesections or blocks are inter-locked and reinforced by metallic bars ormembers 4 and 5, positioned vertically and horizontally and embedded inthe concrete of the blocks as the latter are being built up from theconcrete material, as seen particularly in Fig. 1, at the point of theomission of a block or section for that purpose. These reinforcingmembers 4 and 5 are themselves secured in position, when applying theconcrete material therearound, by means of brackets or lugs 6 of generalangular formation, each having a laterally projecting terminal 6 and anoppositely projecting shoulder 6 a short distance from said terminal; anut equip 36d bolt 7 being inserted through apertures 7 of a pair ofbrackets, after passing stem-terminals of said brackets throughapertures 7 in said reinforcing metallic bars, all as seen particularlyin Fig. 4. The laterally projecting terminals 6 and the shoulders 6 ofthe pairs of brackets 6, it will be observed, fit upon opposite sidesofthe reinforcing metallic bars, 5 and thus provide for clamping thebrackets, without the aid of additional means, in position to saidreinforcing'bars.

In applying or attaching the brackets to the reinforcing andinterlocking bars, they are slightly moved out of a right angledposition to the reinforcing bars and in that position enabled to bepassed through the holes 7 of the latter, the brackets then beingadapted to be positioned, with the laterally extending terminals andshoulders of said brackets brought fiat against the reinforcing bars.

It is obvious that the various joints between the parts, all beingsuitably filled in with concrete as conventionally indicated moreparticularly in Fig. 1, the same will present a water proof structure asrequired for its intended purpose It is thought that from the foregoingmy invention, both as to construction and application, will be readilyand fully understood.

Various changes in the form, proportions and minor details ofconstruction may be resorted to without departing from the principles orsacrificing any of the advantages as defined in the appended claim.

Having described my invention. what I claim as newand desire to secureby Letters Patent, is

An improvement in the construction of pipes of the character described,including a block of general arcuate outline having its ends formed withstepped terminals, forming shoulders thereon, said block also beingtransversely stepped, providing shoulders along its inner upper andlower edges and along its outer upper and lower edges, said shouldersbeing adapted to form overlapping joints with correspondingly formedshoulders on contacting blocks in the pipe formation and interlockingmeans for the block comprising embedded reinforcing metal members andangular brackets, each having a laterally extending terminal and anoppositely extending shoulder-forming projection spaced with respect tosaid terminal to receive therebetween said reinforcing members and acoupling means between said angular brackets.

In testimony whereof I aflix my signature.

JOHN C. POLING.
